Yesterday saw Yamanaka step up his sparring in a big way as he took part in his first 10 round spar, and whilst there was positives to take from the session it does seem like there wasa lot of negative from it too, with Yamanaka showing fatigue in his legs late in the session.
To begin with he looked sharp, made the most of his jab, something that has been lacking in some of his recent bouts, and looked as heavy handed with his left hand as ever. But as the session went on he began to look slower on his feet and it's seems likely that he needs a short rest befor egetting back to doing long spars.
Despite being a bit more worn out than usual Yamanaka seemed calm, and happy that he had had a quality work out ahead of the upcoming Nery bout.
